If you write content in the first line above the default Microsoft email signature, the recipient will not see the content.
We recommend switching to the Outlook add-in, which displays the email signature when composing emails and doesn't reroute your emails.
It's difficult to add content by mistake in the first line above the email signature.
When you click to add the body text, you will always enter the second line, and there are no problems.
You must click twice to enter the first line above the email signature.
We designed the server-side method to search for the HTML tag and replace its contents.
The Outlook app includes the first line inside the HTML tag:
<html>
<br />THIS TEXT WILL NOT SHOW AT THE RECIPIENT END
<br />Get Outlook for iOS
</html>
We did it to ensure that any changes made to the email signature (by the end user) would be overwritten.
For example, if an end user adds 'John Doe', it would be replaced when he sends the email.
And if an end-user removes their email signature in Settings, it will still have an email signature applied because the HTML tag remains (though invisible).
